Two rounds of severe weather occurred on July 25th.  The first round developed during the afternoon hours as instability increased and scattered severe storms developed and tracked across Iowa, northern Illinois and extreme southern Wisconsin.  One pulsing storm produced damaging downburst winds which toppled large trees on a golf course southeast of Monroe.  One strong supercell storm crossed into Wisconsin and propagated into Rock County where it nearly stalled and began backbuilding.  Rotating wall clouds were reported across Rock County by law enforcement.  Golf ball sized hail (1.75") was reported from 1 NE Milton to 7 NE Milton at 1500CST, resulting in extensive crop damage.  Downburst winds were reported west, north, and northeast of Milton.  At 1507CST a rain-wrapped tornado developed 4 NNE Milton and traveled east to 5 NE Milton where it dissipated at 1511CST.  Some structural damage resulted, and winds were estimated around 85 knots (100 mph), giving this tornado a F1 ranking.  Other thunderstorms developed across Columbia and Dodge counties, producing mainly funnel clouds.The second round of severe weather came with the cold front after 2100CST.  A line of severe thunderstorms, with some bowing segments, developed and pushed through south central and southeast Wisconsin during the late evening.  Damaging winds, which toppled large trees, with some large hail, were noted with this line.  A thunderstorm with estimated wind gusts of 65 knots (75 mph) caused a tree to be uprooted and land on a house in Baraboo at 2110 CST, causing 20,000 dollars in damage.  Near Hartford, a 20 by 20 foot section of a barn door was blown off as well as a roof of a storage garage.  A 100 by 30 foot corn patch was also flattened.  Elsewhere, scattered reports of tree damage were reported.
